FABRIC FOR OIL WICKS.

Specification of Letters Patent. Pgyfi qg mtgdl Jan 11(1) 1922 Application filed December 27, 1920. Serial No. 433,394.

type, described in my Patent No. 1327858,

dated January 13th, 1920.

The primary object of my present invention is to provide a woven asbestos wick .wherein the strands are reinforced by a wire core, to materially increase the life of the wick, and to render the same of sufficient rigidity, whereby it would maintain its normal shape under high temperatures to which it is subjected under ordinary usage. In wicks of this particular type, practice has demonstrated that in order to form the asbestos strands from which the wick is woven, a certain small percentage of cotton constituting a binder is necessary, due to the fact that pure asbestos fibre is comparatively of short lengths, and hence, for example, a portion of cotton fibre is used. approximating 10 or 15%. fhe result in the use of the cotton, in woven wicks, is that the heat to which the wick is subjected, will result in the partial consumption of the cotton, whereby the wick, as'a whole, becomes flabby and has a tendency to contract or sag about its burning edge.

By adding a wire strand in the form of a core to certain or all of the asbestos strands, the above objectionable features are overcome, as the metal core thus forms a rigid backbone, upon which the woven structure is built, and whereby it will maintain its normal shape under long usage.

llith the above objects in view, the invention consists in certain peculiarities of construction and combination of parts, as are hereinafter fully set forth with reference to the accompanying drawings and subsequently claimed.

In the drawings,

Figure 1 represents a fragmentary side elevation of a wick upon a magnified scale, embodying the features of my invention.

Figure 2 is a diagrammatic plane view of the wick strip showing the same in circular form adapted to be nested about its burner,

is mixed with it.

I it being understood that when the wick is so nested the reinforced ends thereof are lapped, and 1 Figure 3 is a detail magnified view of one of the asbestos strands from which the wick is woven, the same illustrating the method of manufacturing the strand. j

Referring by characters to the drawings, and as best shown in Figure 1, 1 represents a woof and 2 the warp threads of a woven wick strip, which may be of any length and width. In this exemplifioation of my invention, both the woof and warp strands have central wire cores 3, about which the asbesT tos fibre which form the strandsare fitted. As best shown in Figure 3, the asbestos strands are formedjby first twisting threads as of the asbestos material in long lengths, and in order to add the strength to the asbestos fibre strand, a small percentage of cotton After these strandsare formed, they are wrapped about the wire core 3, as shown, and thus the woven strands. thereafter are utilized to produce a wick strip of the desired length and breadth, as shown in Figure 1. The wick strips are preferably provided with reinforcing end Y my invention, I may in some instances weave the wick strips in circular formation, and, while I have shown and described both the warp and woof as having metal wire cores, 1 may in some instances use the wire cores only with the warp strands or vice-versa.

It will also be observed that while I have shown the asbestos thread as wrapped about the core wire to complete the strand, obviously the wire and thread may, in some instances, be coiled about each other in various manners to complete the strand, without departing from the spirit of my invention.

Furthermore, I may without departing from the spirit of my invention substitute, in some instances, material other than asbestos for the strands having reinforcing core a burner comprislng a series of woven asbestos strands each strand having its own 4;.
